Description
Technical Field
[0001] The utility model relates to a punching mechanism of a fruit punching machine and belongs to the technical field of fruit punching machines. Background Art
[0002] Preserved fruit is also called preserved fruit, and was called honey fried in ancient times. It is a fruit food made from molasses by the Han people. It is spread all over the country and has a long history. Preserved fruit is a food made from fruits and vegetables such as peaches, apricots, plums, dates, winter melons, ginger, etc., which are marinated with sugar or honey. In addition to being eaten directly as a snack or snack, candied fruit can also be used as a garnish on cakes, biscuits and other desserts. The production process of candied fruit is mainly to ensure that the marinade can enter the fruit and realize the marinating of the fruit. However, for some products in which the whole fruit is marinated, due to the obstruction of the peel, it is difficult for the marinade to completely enter the fruit pulp during the marinating process, and the marinating effect of the whole fruit is poor. In order to improve the marinating effect of the fruit and improve the taste and mouthfeel of the finished candied fruit, it is necessary to pierce the fruit so that the fruit can be marinated.
[0003] Fruit punching is generally performed by a fruit punching machine, the main component of which is a punching mechanism with a needle. The punching mechanism in the prior art has the following disadvantages:
[0004] 1. Fruits are big and small, and the highest point of the hard fruit core is sometimes high and sometimes low during the rolling process. Since the punching needle is fixed on the punching mechanism, it is difficult to control the active stroke of the punching needle when punching the fruit with the punching needle. The lower the punching needle is, the easier it is to pierce the fruit core and break the punching needle. The higher the punching needle is, the shallower the depth of penetration into the fruit flesh is.
[0005] 2. The punching needle in the prior art is fixedly installed on the punching mechanism. When the punching needle becomes blunt or broken and needs to be replaced, it is not convenient to disassemble.
[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0028] like Figure 1-3 As shown, the utility model provides a punching mechanism of a fruit punching machine, comprising an upper mounting groove 1, wherein the upper mounting groove 1 comprises a horizontal top plate 101, and four sides of the horizontal top plate are provided with side plates 102 extending vertically downward, and a lower mounting plate 7 is fixedly provided at the bottom of the side plate 102, and a plurality of pinholes are respectively provided on the horizontal top plate 101 and the lower mounting plate 7, and the pinholes of the horizontal top plate 101 and the lower mounting plate 7 are respectively provided in a one-to-one correspondence;
[0029] Punching needles 2 are inserted into the corresponding pinholes of the horizontal top plate 101 and the lower mounting plate 7, and a retaining ring 6 is fixed near the middle of the punching needle 2. Figure 3 As shown, the retaining ring 6 is arranged on the upper side of the lower mounting plate 7, and the punching needle 2 is provided with a compression spring 5 on the upper side of the retaining ring 6.
[0030] A positioning nut 3 is installed on the needle hole of the horizontal top plate 101. The positioning nut 3 is axially penetrated with an avoidance hole 303. The punching needle 2 is slidably set in the avoidance hole 303. The lower end of the compression spring 5 is pressed against the retaining ring 6, and the upper end is pressed against the lower end of the positioning nut 3.
[0031] The compression spring 5 compresses the retaining ring 6 by elastic force, so that the retaining ring 6 presses against the mounting plate 7. When the tip of the lower end of the punching needle 2 hits the fruit core, the retaining ring 6 pushes the compression spring 5 to contract, and the punching needle 2 rebounds upward, thereby preventing the hard fruit core from breaking the punching needle 2.
[0032] The positioning nut 3 includes a hexagonal section 302 and a screw section 301 connected up and down, the avoidance hole 303 passes through the hexagonal section 302 and the screw section 301, the outer side of the screw section 301 is provided with a thread, the pinhole of the horizontal top plate 101 is a threaded hole, and the positioning nut 3 is threadedly connected to the horizontal top plate 101 through the screw section 301.
[0033] The hexagonal section 302 may be an outer hexagonal structure, such as Figure 4 As shown, it can also be a hexagonal structure.
[0034] When the punching needle 2 becomes blunt or broken, the hexagonal section 302 of the positioning nut 3 is twisted with a wrench to remove the positioning nut 3 and pull the punching needle 2 out from bottom to top, which is very convenient for disassembly and assembly.
[0035] The upper mounting groove 1 is a sheet metal part, and the horizontal top plate 101 and the side plate 102 are formed by bending the sheet metal.
